Abstract
The embodiment of the invention discloses a method and a device for recovering data of solid-state storage hard disk in storage system. The method comprises the following steps: whether the life span of the solid-state hard disk reaches a preset upper limit is judged according to the life-span parameter of the solid-state hard disk; when the life span of the solid-state hard disk is over, the data in the solid-state hard disk is stored into a backup hard disk of which the life span is not over yet; and the backup hard disk is switched to for continuing operation. Therefore, the invention reduces unrecoverable data loss caused by the ending of the life span of the hard disk.
Description
Technical field
The present invention relates to field of data storage, relate in particular to the restoring solid storage hard disk data method and apparatus.
Background technology
(Solid State Disk SSD) is the abandoning tradition magnetic medium to solid storage hard disk, a kind of technology that adopts electronic storage medium to carry out data storage and read.Owing to broken through the performance bottleneck of traditional mechanical hard disk, thereby had high memory property.In some military systems, high-performance calculation research field outstanding application performance is arranged, and very likely replace some expensive large computer systems.Because the conventional store development can't break through bottleneck of performance for many years all the time, solid-state storage is considered to the technical renovation of storage industry of future generation, and not only that, some insiders are defined as solid-state storage and change one of five following technology.Think that it has the potentiality of developing new frame in the storage industry field.Two great development branches have also been formed on the developing direction of solid-state storage gradually.A kind of solid-state storage array that is based on RAM medium (memory medium), this novel storage products based on the memory principle is developed by ram disk, the memory capacity 16-128G that general separate unit capacity provides does not wait, product behind the composition array can reach TB (Trillionbyte, terabyte) rank.An other class then is based on the solid-state storage product of flash media (USB flash disk medium).At present, the main product on the solid-state storage market can adopt inner UPS (Uninterruptible Power System, uninterrupted power source) electric power system and the protection of outside ups power usually.The battery that similar our radio frequency identification marking of inner UPS is signed, shape may be also different according to producer's difference.Outside UPS then is similar to the ups power that our server is used, for solid-state memory system provides power down protection.At present, most of solid-state storage producer all adopts two kinds of patterns to use simultaneously, to pursue the data security of higher level.
For traditional disk or tape storage mode,, recover perhaps can also save a part of data by data if damage has taken place storage medium; But for existing solid state hard disc, if flash chip is damaged, that almost is exactly impossible to want to give data for change in the flash chip that is broken into several lobes or is punctured by electric current.The restorability of data.When close to an end the serviceable life of solid state hard disc in the existing storage system, do not carry out the processing of automatic restore data.
The inventor is in realizing process of the present invention, and find that there is following shortcoming at least in prior art: existing solid hard disk storage system lacks the function of automatic restore data, can cause expendable loss of data when terminate the serviceable life of solid state hard disc.
Summary of the invention
The embodiment of the invention provides the restoring solid storage hard disk data method and apparatus, makes memory device possess the function of automatic restore data.
The embodiment of the invention provides a kind of restoring solid storage hard disk data method on the one hand, may further comprise the steps:
Read the parameter in serviceable life of solid state hard disc;
According to the parameter in serviceable life of described solid state hard disc, whether reach preset upper limit the serviceable life of judging described solid state hard disc;
If reach preset upper limit the serviceable life of described solid state hard disc, trigger the data of backup hard disk and recover, make the data of described solid state hard disc copy to the backup hard disk.
The embodiment of the invention provides a kind of restoring solid storage hard disk data device on the other hand, it is characterized in that, comprise: controller system memory, host interface controller and hard disk interface controller, controller system memory, host interface controller and hard disk interface controller pass through interconnects;
Described host interface controller is used to receive the data and the control command of external host, and the operation store system controller carries out data and recovers;
Described controller system memory reads solid state hard disc according to the data and the control command of host interface controller by hard disk interface controller parameter in serviceable life; According to the parameter in serviceable life of described solid state hard disc, controller system memory judges whether reach preset upper limit the serviceable life of described solid state hard disc; If reach preset upper limit the serviceable life of described solid state hard disc, controller system memory recovers by the data that hard disk interface controller triggers the backup hard disk, makes the data of described solid state hard disc copy to the backup hard disk.
The embodiment of the invention is by the parameter in serviceable life according to described solid state hard disc, whether reach preset upper limit the serviceable life of judging solid state hard disc, the serviceable life of solid state hard disc is when terminating, with wherein deposit data in serviceable life also unclosed backup hard disk, and switch to continuation operation on the backup hard disk, reduced the expendable loss of data that serviceable life, termination caused owing to solid state hard disc.
